A Palestinian man was shot to death by Israel Navy forces Sunday after the vessel he was on sailed past the authorized fishing zone off the northern Gaza Strip, the Israel Defense Forces said.

According to an IDF spokesman, the boat, which was carrying three men, did not respond to calls from the Israeli military before the latter opened fire. The two other men on board were detained for interrogation.

The Ministry of Health in Gaza said it has yet to be informed of any casualties or admissions to hospitals in the Strip.

The Gaza Fisherman's Union identified the three men as Mahmoud Adel Abu Riala, 18, Ismail Salah Abu Riala, 18, and Ahed Hassan Abu Ali, 26. The head of the union said he was aware that a fisherman's boat had been seized by the Israeli military, but that he did not know where the fishermen had been taken.

"We are sure that the wounded are fishermen who went out to sea to make a living – and nothing else," he said. "The [Israeli] army is always inventing stories about crossing [out of] the fishing zone."

A similar incident occured last month when the Egyptian navy opened fire on a Palestinian fisherman at sea and killed him. While it could not be confirmed whether the fisherman was attempting to cross into Egyptian waters, Egyptian naval forces have previously opened fire on Gazans they accused of crossing the maritime border.
